x402-gated employee data endpoint on Base, pay-per-request with USDC.
What it does
This endpoint at lowpaymentfee.com serves employee data behind an x402 paywall. The specific resource `/api/v1/employees/14` returns JSON data for employee record #14 when a valid X-PAYMENT header is provided. Payment is settled on the Base network using USDC (contract 0x8335…2913) via the x402 "exact" scheme.
The endpoint charges a maximum of 20,000 base units of USDC per request. Since USDC uses 6 decimals, this translates to $0.02 per call — consistent with the provider's advertised flat pricing of $0.02/request across all their APIs. The provider advertises no API keys, no rate limits, and instant access. The x402 challenge specifies a timeout of 300 seconds.
The broader lowpaymentfee.com platform offers a range of x402-gated APIs spanning data/analytics, AI/ML (sentiment, summarization, classification, embeddings), finance/Web3 (price feeds, exchange rates, token quotes, gas estimates), and infrastructure utilities (geocoding, validation, conversion, generation). However, this specific listing covers only the `/api/v1/employees/14` endpoint, which appears to be an employee data resource. Documentation beyond the landing page is minimal — the docs, API, pricing, and README pages all render only a "Connect wallet" prompt with no substantive content.

Quality
The endpoint is live (402 challenge captured) and pricing is clear ($0.02/request in USDC on Base). However, there is no OpenAPI schema, no response examples, no documentation beyond a landing page, and the employee data resource is not described anywhere on the site. The endpoint path suggests a demo or sample resource rather than a production data service.
Warnings
- —No OpenAPI or schema documentation available for this endpoint.
- —The /docs, /pricing, /api, and /README pages all render only 'Connect wallet' with no usable content.
- —The /api/v1/employees/14 path is not listed among the provider's advertised APIs on the landing page, raising questions about whether this is a demo or orphaned resource.
- —No response schema or example response is available — the actual data returned is unknown.
